Unwanted Position Changes

I am doing a project for school using AE CS3, just making a simple title-esque screen with particle, 3d layers, and thats about it.
I have a camera setup and linked to a null layer, but for whatever reason during one part of my animation, it seems to drift. I've deleted and re-animated, but it still shifts, even when the two key's are exactly the same data-wise.
Im not sure if there is something silly and easy, or perhaps something that I jut didnt do right, but either way im open to help and suggestions!
If you need more info, project files, or screenshots, just let me know!

You can change the default spatial interpolation to linear in Preferences > General > "Default Spatial Interpolation to Linear" (it's the 4th checkbox down the list). I like to do this because it gives me more predictable motion, I can then use my pen tool to go into any motion path and add bezier curves or additional points.

[shane ernest]".....during one part of my animation, it seems to drift."
Steve's suggestion will work.
But let's say you don't want your animation to "bump" to a stop and resume suddenly. Let's say you want the motion to ramp to a stop and ramp up to speed again. Simply highlight the keyframe where the animation stops, and use the Toggle Hold Keyframe command.
Boom. Done. When AE encounters the next keyframe, the position will start up smoothly again. This trick works ONLY if you have two keyframes with identical values, so be careful.
